rllhis invention relates to wrapping machines and has .particularreference to mal Aless series .of pushers each of which is designed topush a leaf in to position to be operated uponvby wrapping mechanism.The said slideway and base member are at an angle to each other, theVlatter having side walls to guide the loaves as they are pushed in.

In machines of this character, it sometimes happens that a loaf arrivesfrom the slideway on the outer: portion ofthe base member of thepassageway leading in to the machine, more or less aslrew, so that whena pusher engages such loaf and starts it along said passageway, theforward end of the loaf contacts with the apex of the angle where theslidcway joins the said passageway. The result is that the continuedmovement of the pusher crushes the loaf. Then it becomes necessary tostop the machine, either manual- 1y or automatically, to remove thedamaged article. This adds to the expense of employing' such wrappingmachines because of not only the loss of some damaged articles'but alsothe time required to remove suoli articles and start the machine again.

The object ofv the present invention is to provide such machines withmeans which will automatically prevent the stoppage of, and damage to,articles on their way from the slideway or first port-ion of the angularpassageway to the second portion or guideway along which the pusherstravel. In accordance with said invention, the said means comprises` awall member at the apex of the angle, which `wall member travels fasterthan thc speed of advance of a pusher, so as to draw a loaf that issomewhat askew away from the pusher andvstart it correctly along i theguideway into the machine.

of the machine `as is necessary to an understanding of the presentinvention. y

liigure 2 is ya diagrammatic plan view of a modification in structure.

Referring first to Figure 1, portion of the frame cf the machine isindicated at 40. it L12 and i3 are represented the lower end portionso-f the .inclined e'ravit slidewa for the es y loaifes. Normally each`loaf arrives against a stop wall la at the far side of thebase member l5of the ,auideway along,` which the loaves are pushed in to the machineto posi tien to be assembled with wrapping paper. The inner side of saidguideway consists of a wall plate 46. @ne ofseries of pushers 48 isillustrated. carried by an endless chain i9 carried by sprockets one vofwhich is illustrated as carried by a driven shaft 51. As se fardescribed, the parts are supposed to be the same as the similarlyindicated parts in Letters Patent No. 1,412,754 hereinbefore referredto.l Reference letters instead of numerals are employed herein todesignate the features of the present invention.

1 arried by the shaft 51 is a pulley a connected by a. belt Y) with asmall pulley c secured to the lower end of a vertical spindle .'Zsuitably mounted in the frame ofthe ma- Said series of pushers are v ingdown the rods Ll2 between the side kbars ---l arrives cn the base d5 notsquared up against the stop wall le but somewhat aslrew illustrated bythe full lines in Figure 1,' then the moment that a pusher 48 engagesits rear end its front end is moved against the periphery of the roll cwhich latter, ro-

tating` at sufficient speed in the direction ofk the arrow, swings thefront end of the'loaf to or toward the dotted line position so that thepusher can cause it to travel smoothly along between the walls 44, 46,and in to be wrapped.

Instead of employing a roll the periphery of which acts on the loaf asdescribed, we may employ a belt as indicated diagrammatically at g5 inFigure 2; Such belt is illustrated as extending around the roll c andaround pulleys 7L, k1, 7b2, so that such belt may not only act in thesaine manner as has been described, but may also act onone end of a loafa? near the lower end of the slide way 42 to increase the tendency ofsaid loaf to reach the stop wall 44, and may also act on'the side of aloaf ai entering the machine to guide it against the wall plate 46.

Having now described our invention, we claim:

1. In a wrapping machine having an angular passageway .for the articlesto be wrapped, a `travelling wall member at the inner apex of theangular passageway to facilitate movement of the articles past saidangle, and means for causing said articles to move singly toward andpast said travelling wall member.

2. In a wrapping machine having an angular passageway for the articlesto be wrapped, a travelling wall member at the inner apex of the angularpassageway, and means for pushing the articles along through the secondportion of said angular passageway.

3. In a wrapping machine having an angular passageway for the articlesto be wrapped, a travelling wall member at the apex of thev angle, andmeans for pushing the articles along singly through the second portionof said angular passageway to start it in a dieren-t direction ofmovement, means being provided for causing said trav- @lling wall memberto movey at a speed higher than the speed of movement of the pushingmeans; Y e

e. In a machine having a guideway and means for pushing articles alongsaid guideway, an inclined slideway at an angle to the said guideway fordelivering articles onto the said guideway, and a travelling frictionmember in position to straighten out an article that arrives askew onthe said guideway.

In testimony whereof we have aixed our signatures.
